I'm using the mrdoob Blender Export Plugin (io_mesh_threejs) to Export to Three JS, but the exported .js or .dae objects do not contain any reference to the texture map files. Is there a special way I need to export the object? Alternatively, is there a special way I need to apply the map to the object in Blender 2.65 in order for the exporter to include it. Lastly, if there is not a way, can I manually add the texture in the JS file?

Reset to default 2I think you can first export your model to .obj from your Blender and then follow the rest part of this tutorial to get your right .json model.
http://bkcore./blog/3d/webgl-three-js-workflow-tips.html
This should be what you are looking for.
http://graphic-sim./B_basic_export.html
Take a look at the example i cooked up .
https://github./master-atul/blender3js
U can see the working example here :
http://www.atulr./blender3js
You can check out my code from my repo link.
And if you wish to know the export options i used :
I directly exported the animations and everything from blender with options described here.

Hope this helps Cheers :)
